unfetch
Bare minimum 500b fetch polyfill
Tiny 500b fetch "barely-polyfill". With a module bundler like rollup or webpack, you can import unfetch to use in your code without modifying any globals. While one of Unfetch's goals is to provide a familiar interface, its API may differ from other fetch polyfills/ponyfills. One of the key differences is that Unfetch focuses on implementing the fetch() API, while offering minimal (yet functional) support to the other sections of the Fetch spec, like the Headers class or the Response class. Uses simple arrays instead of iterables, since arrays are iterables. No streaming, just Promisifies existing XMLHttpRequest response bodies. Use in Node.JS is handled by isomorphic-unfetch. -

JSON5
JSON5 — JSON for Humans
JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. JSON5 was started in 2012, and as of 2022, now gets >65M downloads/week, ranks in the top 0.1% of the most depended-upon packages on npm, and has been adopted by major projects like Chromium, Next.js, Babel, Retool, WebStorm, and more. It's also natively supported on Apple platforms like MacOS and iOS. Formally, the JSON5 Data Interchange Format is a superset of JSON (so valid JSON files will always be valid JSON5 files) that expands its syntax to include some productions from ECMAScript 5.1 (ES5). It's also a subset of ES5, so valid JSON5 files will always be valid ES5. This JavaScript library is a reference implementation for JSON5 parsing and serialization and is directly used in many of the popular projects mentioned above. -

DefiantJS
Provides the ability for you to build smart templates applications
Do you need to query large JSON structures? Do you end up coding loops to parse the JSON and identify the data that matches your query? Defiant offers a better way. Defiant extends the global JSON object with a "search" method that enables lightning-fast searches using XPath expressions. Try out the XPath Evaluator to get the idea. DefiantJS provides the ability for you to build smart templates applicable on JSON structures, based upon proven & standardized technologies such as XSLT and XPath. As of v2.0.0, Defiant can be utilized in the Node.js environment. Since there is no default support for XML technologies in Node, the library puppeteer is initiated to mimic the browser environment, with Defiant running. All methods called from Node is piped via Puppeteer. Even though, Defiant now can be used in the Node environment - utilizing Defiant in the browser is recommended. It all boils down to whether you want your servers to run thousands of searches for your clients. -

Himalaya
JavaScript HTML to JSON Parser
Parse HTML into JSON. Himalaya bundles well with Browersify and Webpack. Himalaya transforms HTML into JSON, that's it. Himalaya is synchronous and does not require any complicated callbacks. Himalaya does not cut corners and returns an accurate representation of the HTML supplied. To remove whitespace, post-process the JSON; check out an example script. Himalaya can include the start and end positions of nodes in the parse output. To enable this, you can pass parse the parseDefaults extended with includePositions: true. Himalaya provides a stringify method. The following example parses the HTML to JSON then parses the JSON back into HTML. -

JSONPlaceholder
A simple online fake REST API server
JSONPlaceholder is a free, fake online REST API designed for prototyping, tutorials, and UI demos without standing up a real backend. It provides predictable endpoints for resources like posts, comments, albums, photos, todos, and users with realistic data shapes. Because the data is publicly available and stable, you can build fetch logic, paginate, and render lists while focusing on front-end patterns rather than server plumbing. The API accepts typical HTTP verbs and returns JSON in a consistent format, making it easy to swap with a real server later. It’s widely used in examples, workshops, and automated tests where a dependable dummy service accelerates iteration. With zero setup, it removes a major friction point for learning HTTP clients and front-end data flows. -

Serialize JavaScript
Serialize JavaScript to a superset of JSON
Serialize JavaScript to a superset of JSON that includes regular expressions, dates and functions. The code in this package began its life as an internal module to express-state. To expand its usefulness, it now lives as serialize-javascript — an independent package on npm. A primary feature of this package is to serialize code to a string of literal JavaScript which can be embedded in an HTML document by adding it as the contents of the script element. In order to make this safe, HTML characters and JavaScript line terminators are escaped automatically. -

Vue Json Pretty

fast-json-stringify
2x faster than JSON.stringify()
fast-json-stringify is significantly faster than JSON.stringify() for small payloads. Its performance advantage shrinks as your payload grows. It pairs well with flatstr, which triggers a V8 optimization that improves performance when eventually converting the string to a Buffer. -

lowdb
Small local JSON database powered by Lodash
Small JSON database for Node, Electron and the browser. Powered by Lodash. You can use any of the powerful lodash functions, like _.get and _.find with shorthand syntax. Lowdb is perfect for CLIs, small servers, Electron apps and npm packages in general. It supports Node, the browser and uses lodash API, so it's very simple to learn. Actually, if you know Lodash, you already know how to use lowdb. lowdb doesn't support Cluster and may have issues with very large JSON files (~200MB). A UMD build is also available on unpkg for testing and quick prototyping. Database lodash instance. Use it to add your own utility functions or third-party mixins like underscore-contrib or lodash-id. With lowdb, you get access to the entire lodash API, so there are many ways to query and manipulate data. -
